Be. it known t a I, GE R E. E rm irr- I-IQFE, a citizen of the UnitedStates, residing at Cuyahoga Falls, in the county of Summit and State ofOhio, havev invented a new and useful, Penholder; and I doherebydeclare. the following to be a full, clear, and exact descriptionof theinvention, such as will enable others skilled in the art to which itappertains tov make and use the same.

This invention, relates to. new and useful pen-holder.

As one of the objects of the. invention, it is the aim to construct the.pen point clamping tube in. one piece, which is adapted to he le P n PQn b twe the tu e 31 9 119 stick.

' Another object ot the invention is to, provide a, reversible clampingtube.

Further, it is an object of the invention to provide a device orclamping tube for holding pens of varying thicknesses.

Another object ofthe, invention is. to, pro- Vide slots at the end ofsaid. clamping tube, said slots are of difierent lengths, and arrangedin staggered relations.

As a further object of the inventionis the provision of spring arms atboth, ends of the. clamping tube, the spring arms at one end being atright angles or in staggered relation with those. 9f the oppositev end.

Another object of the. invention, is the provision Off]. stickhaving areduced portion, at one part of which reduced portion, the diameterthereof is increased, whereby the spring arms of either end of theclamping tube are spread apart, or may frictionally engage the portionof increased; diameter, to hold thetube in place.

Further, another object, is the. provision of an annular shoulder atoneend of said reduced portion, in order to limit the tube, when beingslipped or telescoped, on the stick. p

A further object of the invention is the provision of anothershoulderupon said stick, to limit the penpoint, when being in-' sertedbetween the tube and the stick. 1

A further object of the invention is the provision of an inexpensive,durable, simple, and desirable practical pen-holder, and one which canbe easily cleaned, and the parts thereof disassembled readily.

In the drawings there are disclosed certain features of construction,but in practical fields these features may necessitate alterations, towhich the patentee is entitled, provided the alterations fall within thescope of what is claimed. v j

'The invention comprises further, features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings; Figure 1 is a View in perspective, showingthe improvedpen holder constructed. in accordance with the invention. Fig. 2 is a:sectional view on line 2 2 of part of Fig. 1. Fig. 3 is a detail viewofthe clamping tube.

Referring more particularly to-the drawingsl designates the pen-holderstick, which tapers, as shown, at one end, while the other end isprovided; with a reduced portion .2, and a, shoulder 3 adjoining one endof the reduced portion, This, reduced portion at 'one end; fromsubstantially a to Z) is of a larger diameter in cross section, than thepart between a and the end of the holder. This part between a and, Z)constructed so that the spring arms 5 (which are provided owing to theprovision of the slots 6 may engage therewith frictionally, in, order toholdthe clamping tube against die-Placement. When the spring arms 5engage said enlarged part of said. reduced portion, they are spreadapart slightly, asfdisclosedin Fig. 2 clearly. A slight distance beyondthatportion designated by the letter a, the reduced portion is, providedwith an, annular shoulder 7 and from this shoulder 7 the reduced portiontapers slightly as shown, so that a pen point 8 may easily enter betweenthe tapered end of said reduced portion and the arms 9, yet frictionallyenough, as to hold the point securely in position. These arms 9 areprovided, owing to the construction of the slots 10.

The clamping tube is designed to. be con structed of any suitable springmetal, in order to lend resiliency or yieldability to the arms 5 and- 9.The arms'of either end of the tube are designed for the purpose. ofholding either the tube or the pen point in place. In other words, thetube is reversible, and in that case pen points, varying in length aswell as in thickness may be clamped firmly in place. For example, if thetube is adjusted, so that the arms 5 are used for clampingthe pen point,the point cannot be inserted very far in the holder, be cause of theshortness of said arms, and

yieldability is greatly lessened. Inother words, the nearer the penpoint is inserted to the base of said spring arms 5, the less the saidarms will yield at their base portions. The spring arms9 are designedfor holding varying lengths of pen points, preferably the greater partof the longer pen points, while the arms 5 hold the shorter points. Thearms of either end of the tube are long enough to engage the partbetween a and b of the holder, to hold the tube in place, or are longenough to hold a penpoint against the lower end of the holder. Theobject for making the slots and the arms at right angles to one another,or in staggered relations, is to lessen the chances of weakening theclamping tube, which would occur if the slots and the arms alined withone another.

From the foregoing it is to be ascertained that there has'been devised anovel, simple, efficient and inexpensive and desirable practicalpen-holder, and one which may be disassembled readily for cleaning thesame.

. The invention having been set forth, what is claimed as new and usefulis 2- 1. In combination, a stick having a reduced-portion, a part ofwhich at one end is of one diameter and terminating in a shoulder, whileanother part is of a smaller diameter at the. other end, said smallerportion terminating in a shoulder, a clamping tube telescoping saidreduced portion and provided with spring arms at both ends, the springarms of one end adapted to frictionally engage the larger portion, whilethe spring arms of the other end are adapted to clamp a pen point to thesmaller part of the reduced portion.

2. In combination, a stick having a reduced portion, a part of which atone end is of one diameter and terminating in a shoulder, while anotherpart is of a smaller diameter at the other end, said smaller portionterminating in a shoulder, a clamping tube telescoping said reducedportion and provided with spring arms at both ends,"the spring arms ofone end adapted to frictionally engage the larger portion, while thespring arms of the other end are adapted to clamp a pen point to thesmaller part of the reduced portion, the first shoulder adapted to limitthe clamping tube, while the second shoulder limits the pen point.

3. In combination, a stick having a reend may be adapted for clamping. apen duced portion, a part of which at one end is of one diameterandterminating in a shoulder, while another part is of a smaller diameterat the other end, said smaller portion terminating in a shoulder, aclamping reversible tube telescoping said reduced portion and providedwith spring arms of different lengths and corresponding slots at bothends, the spring arms at one end being at right angles or in staggeredrelations to those of the opposite end, the spring arms of one endadapted to frictionally engage the larger portion, while the spring armsof the otherend' are adapted to clamp a pen point to the smallerpartofthe reduced portion, the firstg shoulder adapted to limit theclamping tube, while the second shoulder limits the pen point. 7

4;. In combination, a pen holder stick having a reduced portion, aclamping tube having spring arms at both ends telescoping the reducedport-ion, said clampingtube being reversible, in order that the arms ofeither point, the spring arms of one end being of diiferent lengths toand arranged at right angles to the arms of the opposite end, the armsof either end being long enough to en gage the reduced portion toholdthe tube in place. v

5. In combination, a pen holder stick having a reduced portion, aclamping tube having spring arms at both ends telescoping the reducedportion, said clamping tube being reversible, in order that the arms ofeither end may be adapted for clamping a pen point, the spring arms ofone end being of different lengths to and arranged at right angles tothe arms .of the opposite end, the arms of either end being long enoughto engage the reduced' portion to hold the tube in place, the pen holderstick having means to limit the clamping tube in telescoping the same onthe reduced portion, while the reduced portion is provided withmeans tolimit a pen point when inserting the same between the spring arms at oneend and the reduced portion.

In testimony whereof I have signedmy name to this specification in thepresence of two subscribing witnesses.
